SMUDGING APPARATUS.

Specification of Letters Patent.

Patented Nov. 36, 1915.

Application filed July 25, 1914. Serial No. 853,228.

as (punk or other compositions of matter ma e up in the form of briquets, and by means of which just suicient oxygen will be supplied to the punk to cause it to burn continuously, slowly and uniformly, and thereby produce a smudge or fume which may be employed for inhalation purposes in the treatment of nose and throat disorders, or in disinfecting or deodorizing, and which,

when constructed on a larger scale, is adapted for use in smudging fruit trees and plants to protect them from frost.

A further object is to provide a smudging apparatus which is simple in construction and so builtand arranged as to eliminate the danger ofinflaming materials coming in Contact with the structure and at the same time protect the burning substances in the structure from the effect of strong air currents.

The invention is illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of the smudging apparatus. Fig. 2 is a vertical section of same, partly in elevation. Fig. 3 is a plan view.

More specifically, 5 indicates a circular base member having a central upwardly projecting portion 6 formed with an upwardly convergent outer wall. Mounted on the upper face of the base member 1s a series of upward-ly extending spaced spring fingers 7 arranged around the center of the portion 6 -and securedthereto by means of screws 8 or other suitable fastenings.

lThe spring fingers 7 form a means for engaging a briquet 9 of slow burning, noninflammable material, such as punk, containing such ingredients as are desired according to the use to which the apparatus is to be put. Mounted on the basc' and encompassing the portion 6 in frictional engagement with the tapered walls of the latter 1s a frusto-conoidal liuc or stack 10 preferably formed of sheet metal and open at its upper end a suitable distance above the briquet 9. The'stack 10v is slidably engaged with the portion 6 of the base 5 and is adapted to be readily removed lwhen it is` desired to gain access to the briquet 9 to ignite or ren ew the latter and to be replaced when putting the apparatus in operation.-

Encircling the inner wall of the stack 10 is acorrugated sleeve 11 formed of an insulatlng material, such as sheet asbestos, or paper in some instances; the corrugations of the sleeve 11 extending longitudinally thereof and terminating at the upper end of the sleeve iiush with-or adjacent to the upper edge of the stack 10 and terminating at the lower edge of the sleeve a short distance above the upper face of the base portion 6. Y

` Mounted on the stack 10 within the sleeve 11 is a tapered cylinder 12 the outer walls of which abut against the corrugated sleeve 11; the cylinder 12 being secured in place in any suitable manner, being here shown as attached to the stack 10 by means of pins 13 which pass through the walls of the stack 10, sleeve 11, and cylinder 12, and are turned over on their ends interiorly of the cylinder and exteriorly of the stack. The lower end of the cylinder 12 is open and the marginal edge thereof is spaced above the upper face of the portion 6 of the base substantially in alinement with the lower edge of the sleeve 11. The upper end' of the cylinder 12 is formed with a top plate 14 extendingush with the top of the stack 10 and having .a

central circular aperture 15 therein. A

In the operation of the invention, the stack 10 is removed from the base 5 and the briquet 9 is placed in engagement with the fingers 7 and ignited. rlhe stack 10 is then replaced as shown in F ig. 2, whereupon the burning of the briquet 9, which is slow and without flame, creates a smudge or heated vapor within the cylinder 12 which rises in the latter and passes out through the aperture 15 in the upper end 14E thereof as indicated by the arrows. This action creates a draft in the cylinder 12, thereby drawing air downwardly between the corrugatedv portions of the sleeve 11; the air entering entirely throughout the inner circumference of the stack 10 and passing downward on both sides of the corrugated sleeve 12 and under the lower edge of the latter and beneath the lower endf'of the cylinder 12 into the chamberV within the cylinder at a point surrounding and adjacent to the briquet 9. The Walls of the cylinder 12 become heated by the slow combustion of the briquet 9 which heat' radiates into tlie spaces between the inwardly extending corrugatlons on the sleeve 11 so as to superheat the air passing downwardly between isaid corrugations; the HOW of air between the stack l0 and cylinder 12 coperating with the insulating sleeve 11 to maintain-the stack l0 in a coniparatively cool condition so that it may be readily handled and prevent the burning of any substances which may come in contact with the stack 10. i

By forming the cylinder 12 with a top 14 the latter serves to prevent down drafts induced by strong currents of air around the apparatus, from affecting the burning of 'the briquet'Q.

What I claim is:

A smudging apparatus, comprising a base member, briquet holding means thereon, a stack on said base member encircling the briquet holding means, a cylinder form-ed "with an upper apertured end `arranged in said stack with its lower end terminating above the base member7 and a corrugated insulating sleeve interposed stack and tbe cylinder."v I Y y n Witness that I claim the foregoing l have hereunto subscribed my naine this 6th day of July, 1914. y s y PETERSON H.
